Figure 1-26. 15K Self-Recovery Winch (SRW)
When specified, any vehicle except models M1084 and M1086 may be equipped with a 15K Self-Recovery Winch
(SRW) (1, Figure 1-26) mounted on the right hand frame rail. The 15K SRW is rated for 15,500 lbs (68,944 N) pull
when the winch drum has one full layer of cable. One full layer of cable is the minimum amount of cable that may be
left on the drum when using the 15K SRW. Pulling capacity is reduced with each layer of cable that is added to the
winch drum. Pulling capacity with seven full layers of cable on the winch drum is 9,090 lbs (40,432 N). For recovery
operations, the cable may be routed to the front on all vehicles so equipped. The cable may be routed to the rear of
the vehicle on models M1083, M1085, M1090, M1093, and M1094. The 15K SRW is equipped with a fail-safe brake
which is spring applied and hydraulically released. The fail-safe brake is automatically applied when hydraulic pressure
falls below 270 psi (1,862 kPa). The fail-safe brake will hold the load until hydraulic pressure is restored. The winch
control valve functions as a throttling valve when cable is being payed out. The winch control valve controls the flow
of fluid to the winch motor. When cable is being pulled in, the winch control valve acts as a free flow check valve. The
winch control valve is preset at the factory and is not to be adjusted under any circumstances.
